version 0.6 problem

Then I unistalled the 0.5 version and I installed the 0.6 version. From that point Orchard says "Some features need to be upgraded: (link) TheMetroTheme". When click the link "The Metro Theme" it shows the modules admin page. What can
I do next?

I tried to update via the themes admin page, but then Orchard says "An error occured while updating the theme TheMetroTheme: Exception has been thrown by the target of an invocation.". What I made wrong?

The modules for the packages are all enabled (Package Updates, Packaging, packaging commands), but orchard insist to the above behavior. I deleted the folder (of 0.6 version) and then I installed the same version, but the results are the same.
What can I do?

You can try to do thorough cleaning of the theme, following the instructions below:
1) Make a Backup;
2) Set as current an other theme;
3) Delete "The Metro Theme" Directory;
4) Open Orchard Database and Drop "TheMetroTheme_ThemeSettingsRecord";
5) Open table "Orchard_Framework_DataMigrationRecord" in Orchard Database and delete the record that has "TheMetroTheme.Migrations" value in the DataMigrationClass column (Delete From Orchard_Framework_DataMigrationRecord WHERE DataMigrationClass
= 'TheMetroTheme.Migrations')

Now you no longer have references to "The Metro Theme" and you can reinstal v0.6.0 Alpha from the Orchard Gallery.

If the problem persists then you need to look elsewhere and not in the theme.
